Currently, two types of small self-contained deluge systems are in
use in military ordnance facilities. They may be used with the ultra high-speed
deluge systems discussed in this section, or alone if an adequate water supply is
not available for the facility. These small self-contained deluge systems are
primarily intended for personnel protection, although they provide some
building/equipment protection. When used, these systems should be connected
to the existing water supply if the water supply can be of some benefit.
6-9.2.5.1
The portable deluge system is a transportable self-contained ultra
high-speed deluge system. The system uses multiple optical fire detectors,
multiple nozzles, and a pressurized water tank (typically 380 L (100 gallons) of
water). Response time does not exceed 100 ms (detection to water at the
nozzle). The portable system is intended to protect short-term operations. When
possible, connect the portable deluge system to the building water supply for
backup water.
6-9.2.5.2
The pressurized sphere ultra high-speed deluge system is a small
self-contained system. The system uses one or more optical fire detectors, at
least one pressurized (typically 3,447 kPa (500 psi)) water sphere (typically 10 to
30 liters (2.6 to 7.9 gallons)) with a rupture disc and internal squib, and an
electronic controller. Response time is less than 10 ms (detection to water at the
nozzle). The sphere discharges water when the squib fires, opening the rupture
disc. A screen breaks the water into small-atomized particles and collects the
residual squib fragments.
